Introduction to Frontend Development
Frontend development, often referred to as client-side development, is a critical aspect of web development focused on crafting the user interface of a web application. It’s what users directly interact with and involves the creation of content and functionality that runs on a client’s browser. Frontend developers utilize a variety of languages, tools, and frameworks to design and build websites that are responsive, interactive, and visually appealing.
Core Technologies in Frontend Development

CSS (Cascading Style Sheets):
- CSS is used for styling and layout design. It controls the color, font, size, spacing of elements on the webpage. CSS makes the website visually appealing and responsive.
- JavaScript:
- JavaScript is used to add interactivity to web pages. It enables functionalities such as form submission, interactive maps, and animated graphics. It’s essential for creating dynamic user experiences.
